Abstract

A precise positioning method for the motion track of a multiaxis manipulator using PLC technology was developed to enhance workability and efficiency. The system integrates manual, zero finding, automatic, and semiautomatic operational modes, with an action sequence including pitch down, stop rotation, open claw, reach out, close claw, retract, reverse, pitch up, and stop. The control system, based on SIEMENS PLCS7-300, includes a PLC, touch screen, step drive, sensors, and a pneumatic servo positioning device. I/O port distribution was designed, and control code was created to coordinate the step motor and pneumatic devices, ensuring seamless operation. Experimental results indicate a success rate over 98.5% and a breakage rate under 1%, demonstrating robust transmission and antinoise performance for precise manipulator positioning.
